Which cause-effect relation is wrong in India-world relations?

Correct answer: Contact routes made India completely isolated

Direct answer: Option D is the wrong cause-effect relation. India’s favourable geographical position placed it near land and sea routes, and these routes encouraged exchange. Step by step: location creates access; access creates routes; routes allow movement of traders, goods, travellers and ideas; movement increases cultural and economic contact. Option A is correct because favourable location can support routes and routes can increase exchange. Option B is correct because sea routes connected India with regions around the Indian Ocean and supported trade. Option C is correct because land routes carried goods, beliefs, languages, technologies and ideas. Option D is wrong because contact routes do the opposite of complete isolation: they connect societies. The word “completely” is especially problematic, because no network of routes can logically be used as evidence that India was entirely cut off. Remember the chain: location, routes, movement, exchange—not isolation.
